description (continued)
These devices are fabricated using power-saving CMOS technology for high speed and simple interface with
MOS and bipolar circuits. All inputs (including program data inputs) can be driven by Series 74 TTL circuits
without the use of external pullup resistors. Each output can drive one Series 74 TTL circuit without external
resistors.
The data outputs are 3-state for connecting multiple devices to a common bus. The TMS27C512 and the
TMS27PC512 are pin compatible with 28-pin 512K MOS ROMs, PROMs, and EPROMs.
The TMS27C512 EPROM is offered in a dual-in-line ceramic package (J suffix) designed for insertion in
mounting hole rows on 15,2-mm (600-mil) centers. The TMS27PC512 OTP PROM is supplied in a 32-lead
plastic leaded chip carrier package using 1,25-mm (50-mil) lead spacing (FM suffix).
The TMS27C512 and TMS27PC512 are offered with two choices of temperature ranges of 0
°
C to 70
°
C (JL and
FML suffix) and – 40
°
C to 85
°
C (JE and FME suffix). See Table 1.
All package styles conform to JEDEC standards.

These EPROMs and OTP PROMs operate from a single 5-V supply (in the read mode), thus are ideal for use
in microprocessor-based systems. One other 13-V supply is needed for programming. All programming signals
are TTL level. The device is programmed using the SNAP! Pulse programming algorithm. The SNAP! Pulse
programming algorithm uses a V
PP
of 13 V and a V
CC
of 6.5 V for a nominal programming time of seven seconds.
For programming outside the system, existing EPROM programmers can be used. Locations can be
programmed singly, in blocks, or at random.
